TYPO3 suggest wizard, search in substring

I use the suggest wizard in TYPO3 backend.

The following code is in the tca:

'tx_db_colors' => array (
'exclude' => 0,
'label' => 'Farbe',
    'config' => array (
        "type" => "group",
        "allowed" => "tx_db_colors",
        "foreign_table" => "tx_db_colors",
        "internal_type" => "db",
        "size" => 1,
        "minitems" => 0,
        "maxitems" => 1,
        'items' => array(array('', ''),),
        'wizards' => array(
            'suggest' => array(
                'type' => 'suggest',
            ),
        ),
    )
),

Is there a solution, to get matched records in substring of the label, not from scratch?

Example:

The records label is named 'coffee black'

When I type 'co' into the search field, the record will be shown.

'blac' won't match to any record.

Is this possible to find this record, when I type in a substring? Else I have to extend the autocompletion. TYPO3 Core, yuk! :-)

Thank you in advance!

After hours, I found the solution. You have to write the tca like this:

'tx_db_colors' => array (
    'exclude' => 0,
    'label' => 'Farbe',
    'config' => array (
        "type" => "group",
        "allowed" => "tx_db_colors",
        "foreign_table" => "tx_db_colors",
        "internal_type" => "db",
        "size" => 1,
        "minitems" => 0,
        "maxitems" => 1,
        'items' => array(array('', ''),),
        'wizards' => array(
            'suggest' => array(
                'type' => 'suggest',
                'default' => array(
                    'searchWholePhrase' => 1
                ),
            ),
        ),
    )
),

Just add

'default' => array(
    'searchWholePhrase' => 1
),

into the 'suggest' array.
